Got a Westfalia OSD 35-0136-067 design 35 on HFO. Separator is passing oil through sludge outlet during operation. What’s been done already:

- all bowl O-rings replaced

- new belt

- new clutch shoes

- spindle checked, condition very good

- water block replaced and tested

Separator reaches speed normally and sludging cycle works correctly. Bowl seems to open/close as it should. No continuous discharge from operating water/dirty water outlet during separation.

Anyone had similar issue on these OSDs?
